After reading Marching Powder (the book I couldn't put down when we did the boat trip from Panama to Colombia), I was really eager to go to San Pedro and take a look at the prison which is weirdly situated right in the middle of the hustle and bustle of the city.
The prison is completely corrupt and led by bribery and has it's own economy, political system and inmates even have to buy their own cells from the guards!
A few years ago you used to be able to bribe the guards and go into the prison for a tour (hence the book), but they have completely clamped down on security now. So much so that if they see you even taking a photo outside, they will chase you until you have deleted it. I had to take these ones from behind a tree or statue!
When we were there, the families of woman and children that live in the prison with the inmates were all queuing and waiting to be let in after they had been to work and school.
I don't want to spoil it and go into too much detail on it all. But for those who haven't read the book, DO, because it's amazing -
